Arcing horns protect bushings in case of the overvoltage.
Problem Type: 3D electrostatics.
Geometry: 3D import.
Given:
Relative permittivity of air ε_{0} = 1,
Relative permittivity of insulator ε_{r} = 6,
HV V = 6 kV (RMS).
Task:
Calculate electric field stress distribution along the bushing insulator surface and in the spark gap.
Solution:
Results:
Electric field distribution in the spark gap:
